Description

Technical Field

[0001] This utility model relates to the field of steel bar straight thread processing, and in particular to a steel bar straight thread processing device. Background Technology

[0002] Steel bars are a major building material. Due to the limited length of steel bars, several steel bars are usually joined end to end during the construction process. The joining methods include welding and connecting them with connectors by making straight threads. Making straight threads requires a steel bar straight thread processing device to make threads on the surface of the steel bars by rolling threads.

[0003] Patent number CN101831990A discloses a rebar rolling and straight thread joint. First, the end of a ribbed rebar is rolled and extruded into a cylinder, and then a straight thread is rolled onto the end of the cylindrical rebar. Two identical concave rollers roll the end of the ribbed rebar 10 into a cylinder. The longitudinal cross-section of the semi-circular grooves of the two concave rollers is integrated into a circle, with its center line coinciding with the axis of the thread rolling head 3. There are notches on the upper sides of the opposing semi-circular grooves of the two concave rollers, allowing the ribbed rebar and the straight thread rebar end to enter and exit. The two concave rollers rotate at the same speed but in opposite directions, their semi-circular grooves rolling and extruding the longitudinal and transverse ribs of the rebar end, and pushing the cylindrical rebar end outward at a rotational linear velocity. The concave rollers 9 and 11 are jogged and rotated to engage and fix the rebar 10 in the desired position, and then the thread rolling head 3 rolls a straight thread onto the cylindrical end of the rebar. The joint provided by this invention has a tensile strength exceeding that of the base material, and can complete the rolling and straight thread rolling on a single machine, achieving high quality, high efficiency, and low consumption.

[0004] However, traditional straight thread processing devices suffer from poor work continuity. During the processing of steel bars, manual feeding is required for each bar, and after processing, the bar must be removed and then fed again, resulting in low processing efficiency.

[0005] Therefore, this case proposes a rebar straight thread processing device to solve the above-mentioned technical problems. Utility Model Content

[0026] The arrangement structure 7 includes two fixed seats 8 and two movable seats 9. The two fixed seats 8 and two movable seats 9 are symmetrically installed on the upper part of the housing 1. The inner sides of the two fixed seats 8 and two movable seats 9 are respectively rotatably connected to the first connecting rod 10 and the second connecting rod 11. The outer sides of the first connecting rod 10 and the second connecting rod 11 are both fitted with connecting belts 12. Several card seats 13 are fixedly installed on the outer side of the connecting belts 12. A third motor 14 is fixedly installed on the upper part of the housing 1 near the rear. The output shaft of the third motor 14 is fixedly connected to one of the first connecting rods 10.

[0027] In this embodiment, an adjustment structure 16 is provided between the movable seat 9 and the housing 1. The adjustment structure 16 includes a slide groove 17. The slide groove 17 is opened on the upper surface of the housing 1 near the center of the other side. Both movable seats 9 are slidably connected to the slide groove 17 through a slider 19. A lead screw 18 is rotatably connected inside the slide groove 17. The lead screw 18 is threadedly connected to the slider 19.

[0028] The adjustment structure 16 can adjust the position of the two movable seats 9, thereby adjusting the spacing between the two sets of connecting strips 12, making it suitable for steel bars of different lengths and improving the applicability of the steel bar straight thread processing device.

[0029] In this embodiment, a plug rod 15 is fixedly installed at one end of the first connecting rod 10, and a slot is opened on the surface of one end of the second connecting rod 11. The plug rod 15 is compatible with the slot, and the contact surface between the plug rod 15 and the slot is hexagonal.

[0030] After the insert rod 15 is inserted into the slot, it can connect the first link 10 and the second link 11 together, and the hexagonal contact surface can play a limiting role.

[0031] In this embodiment, a steel bar placement groove is provided on the upper surface of the card holder 13, and the steel bar placement groove is V-shaped.

[0032] The "V"-shaped rebar placement groove makes it more convenient and faster to place rebar manually.

[0033] In this embodiment, a guide plate is fixedly installed at the front of the box 1 near the top, and the guide plate is inclined at 45° in the horizontal direction.

[0034] The guide plate can guide the steel bars, allowing them to slide to a specific position.

[0035] In this embodiment, a handwheel is fixedly connected to one end of the lead screw 18 that passes through the slide groove 17, and the contact surface between the slider 19 and the slide groove 17 is "T" shaped.

[0036] The handwheel allows for easy operation of the lead screw 18, and the "T"-shaped contact surface provides vertical limiting.

[0037] In this embodiment, a clamping assembly 20 is provided on the upper part of the box 1 between the two connecting belts 12. The clamping assembly 20 consists of two cylinders. The two cylinders are vertically aligned, and one cylinder is fixedly connected to the box 1. The other cylinder is installed through an external structure. The output shafts of both cylinders are fixedly installed with "V" shaped clamps.

[0038] The clamping assembly 20 can clamp and fix the reinforcing bar during the processing of straight threads, preventing the reinforcing bar from rotating and ensuring the stability of the straight thread processing.

[0039] It should be noted that this utility model is a steel bar straight thread processing device. When in use, the distance between the two connecting strips 12 is adjusted according to the length of the steel bar. During operation, the screw 18 is rotated, and the screw 18 drives the slider 19 to slide inside the slide groove 17. The slider 19 drives the two movable seats 9 to move, thereby adjusting the position of the connecting strip 12 outside the movable seat 9 and adjusting the distance between the two connecting strips 12.

[0040] After adjustment, place the steel bar inside the bracket 13 between the two connecting belts 12, start the third motor 14 to work, the third motor 14 works in a step-by-step manner, and drives the two connecting belts 12 to rotate simultaneously through the first connecting rod 10 and the second connecting rod 11. The two connecting belts 12 drive the steel bar to move through the bracket 13.

[0041] When the reinforcing bar moves between the two "V"-shaped clamping plates of the clamping assembly 20, the two cylinders push the two "V"-shaped clamping plates to move, thereby clamping and fixing the reinforcing bar. At the same time, the second motor 5 works, and its output shaft drives the screw 6 to move. The screw 6 drives the slide 2 to slide, so that the thread rolling head 4 is sleeved on the outside of the reinforcing bar. The first motor 3 works, driving the thread rolling head 4 to work and perform straight thread processing on the reinforcing bar. The thread rolling head 4 refers to the thread rolling head disclosed in patent number "CN101831990A".

[0042] After the thread rolling is completed, the second motor 5 starts working again, driving the slide 2 to reset, the two cylinders to reset, and the third motor 14 starts working, driving the connecting belt 12 to rotate again, sending out the processed steel bars and bringing in the steel bars to be processed, thus realizing continuous work and higher work efficiency.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
